A tongue comprises a housing case in a substantially box form for housing a tongue plate and inclusive of a through hole formed at a position facing an insertion hole of the tongue plate so as to allow insertion of a webbing, and a stopper bar, with a folded portion of the webbing hung therearound, which is arranged striding over the insertion hole of the tongue plate, allowed to slide back and forth with reference to the tongue plate and urged rearward by a urging unit in contact with a pair of front end surfaces on a pair of engagement parts provided at longitudinal ends of the stopper bar. The housing case includes a plurality of ribs arranged upright on an inner surface thereof along a front-rear direction so as to press the webbing which is arranged to face the inner surface and hung around the stopper bar meets. The plurality of ribs are arranged in parallel to one another in a direction orthogonal to a sliding direction of the stopper bar.
